PAPER PUNCH 0R PERFORATOR.

Specification of Letters Patent.

Patented Jan. 7 1913.

Application led October 23, 1911. Serial No. 656,150.

To all 'wh-0m t may concern:

y Be itl known that we, HARRY GoUsINs and.

JOHN WILLIAM BoTsFoRD, subjects of the King of England, both residing at Cardiff,

Wales, have invented certain new and useful Improvements" in .Paper 'Punches or Perforators, of which the'following is a specifi tails which will be hereinafter more .fully punch or perforator for perforating papers'y obliquely `across the corner `and havingV punches for perforatingeither round or recy' tangular perforations at will.

The invention also comprises certain dedescribed.

In the accompanyingv'drawingsFigure l'k is a side elevation in partsectionof a punch adapted to make eitherrectangular or ciry cular perforations at will; Fig. 2 isfan end elevation, and Fig. 8 a plan view of the device.

Like letters indicate like parts throughout.

Referring to the drawings, which show a punch adapted to `make either rectangular or circular perforations at will, on a base A4, of wood or any other material is fixed a metal casting B3 which carries, by means of brackets B4 a pair of punches D3 adapted to punch circular perforations, and a pair of punches D4 adapted to punch rectangular perforations. The lower part "of the punch support B1 also forms a stripper by means of which the perforated sheet is drawn olf the punches as they rise after operating. On the top of t-he casting B3 is pivotally mounted a handle C2. `Fig. 1 shows a circular spring D5 surrounding the punches D3. Fig. 2 shows the method of mounting the spring-member to govern the rectangular punches D4. The punches are connected together at'their upper end by means of a cross-piece D6, and a vertical stud D7 is situated centrally between the punches and is screwed between the two brackets B4 B4. The stud passes through a hole in the crosspiece D, and a spring D surrounds the stud and bears at its lower end against the bracket B4 and at its upper end against the cross-piece De. A plate D9, held in position by means of screws D10 incloses the spring and bolt, and in Fig. 2 the plate is not shown for the sake of clearness. rVhen the pivoted handle C2 is'depressed on either side a projection C3 situated close to the axis of the handle bears against either the circular punches D3 or. rect-angular punches D4. If the handle is further depressed, one pair of punches will be depressed to the limit of their travel, and will perforate the paper placed beneath them.

The base A4 is fitted with a metal platel perforated at points just below the punches, the punches coperating with these perforat-ions or dies. A gage L3 is employed for.4

the purpose of insuring that the papers 0r the like shall be punched in the same yposition for each successivejoperation of the punch. The gage or V-guide is rectangular, and has small holes L4 in its two wings. In the casing B3 are fitted a pair yof screw studs L5 which engage with theholes L4. It is thus possible readily to adjust the rectangular gage L3 to any desired position.

By unscrewing the studs L5 the gage Ls` can bewithdrawn, and replaced in the punch in the reverse direction, thus affording a gage for use with both Vthe circular andrectangular punches.

Papers and the like perforated by'this punch can be fastened, tied or attached together through the holes punched obliquely across the corner by `being either tied together loosely, or tightly by tapes, string, laces, clips or other means. Papers thus secured possess many advantages over other methods, in that papers can be easily turned over and at the same time, securely fastened without the danger of tearing the paper. If the rectangular gage L were removed and replaced by a straight one it would be possible to punch holes at the,V sides or tops of sheets of paper in the known way. n

If desired the punch could be constructed so as vto perf larV perforations at will, by making the punches interchangeable or by the employment of two distinct systems of linkage which could -either be 'operated by the same `or by different handles. The base could be made of any suitable material such as aluorate either round or rectanguminium, or if desired, wood. The plate J is preferably made of steel in order that it shall not get damaged by the raction of the punches. Further, the arm B if desired, could be cast solid with the base A.

What we claim as our invention and desire to secure by Letters Patent is l. In a perforator for sheet material the combination of a base, dies in the base, a plurality of gangs of punches to coperate with the dies, a support for the punches a lever operatively disposed in relation to the punches to operate one gang at a time, a movable guide adapted to position the sheet to be perforated in relation to Whichever gang of punches is to be used so that the holes punched are on a line lying obliquely across the corner of an inserted sheet, and means to hold the guide in correct position.

2. In a pertorator for sheet material the combination ot a base, dies in the base, a plurality of gangs of punches to coperate with the dies a support for the punches a lever operatively disposed in relation to the punches to operate one gang at a time a movable V-guide adapted to position t-he sheet to be perforated in relation to whichever gang of punches is to be operated, and means comprising pins borne by the punch support cooperating with a corresponding number of series of holes in the guide to hold and position the said guide correctly upon the base so that the holes punched are on a line lying obliquely across the corner of the sheet placed in the guide.

3. In a perforator for sheet material the combination of a base, dies in the base, two gangs of punches to coperate with the dies, a support for the punches which also constitutes a stripper, a lever pivoted on the punch support to swing in one plane only, adapted when swung to one side of the pivot to operate one gang and when swung to the other side of the pivot to operate the other gang of punches, and a reversible adjustable V-guide to position the sheet to be perorated in relation to either gang of punches,

and means to hold and posit-ion the guid correctly upon the base.

4. In a perforator for sheet material the combination of a base, dies in the base, two gangs of punches to coperate with the dies, a support for the punches which also constitutes a stripper, a lever pivoted on the punch support to swing in one plane only, adapted when swung to one side of the pivot to operate one gang and when swung to the Vother side of the pivot to operate the other gang of punches, a reversible adjustable V- guide, and means comprising threaded pins adjustably screwed through the punch support and coperating each with a series of corresponding holes in each wing of the V guide to hold and position the said guide correctly upon the base so that the holes punched are on a line lying obliquely across the corner of the sheet positioned by the guide.

5. In a perforator for sheet material the combination of a base, gangs of rectangular punches, gangs otcircular punches, dies cooperating with the punches, a slotted support in which the punches are slidingly mountedv a lever operatively disposed in relation to the punches to operate one gang at a time, means to return the punches to inoperative position, means tor securing the rectangular punches together in a gang comprising a cross piece D, a stud D7 secured in the punch support passing through a hole in the cross piece and guiding a return spring D8 and a retaining plate D9 holding the punches in the slots of said slotted support, and an adjustable reversible guide to position the sheet to be perforated.

In testimony whereof we have signed our names to this specification in the presenceV of two subscribing witnesses.
